Blackburn Rovers boss Mark Hughes is hoping to have Steven Reid and Ryan Nelsen back at his disposal in January.
Rovers were dealt the news Reid would be out for four months on Tuesday, while Nelsen has not played a minute this season after undergoing hamstring surgery.
Reid suffered a stress fracture in his back in September and has been informed he needs a lengthy period out of action recovering from the blow.
Hughes believes Reid and Nelsen were two of the club's most influential players last season and is delighted with how the squad have coped in the absence.
"Obviously it's very, very disappointing for Steven and the squad as a whole because he was a very significant player for us last year," Hughes told Sky Sports News.
"You could argue we've lost our two most influential players this season with the long-term injury to Ryan Nelsen as well.
"So we've coped very, very well with their absence. Obviously ideally we would prefer them to be available but we'll hope to have them back in January.
"It will be January we hope. It's difficult to put a real timescale on it, but that's the indication we've got."
